Why are you using such OP mod , there are many better ways to get energy than using it.
Instead of blaze rods, try getting a wood farm -> charcoal -> generators.
Or you can try one of my (not so) famous Windmill Farms. [Link is at my signature]
I'm still in the experimental stage of my personal modpack, and that one may end up getting cut. I just liked the idea of getting points for killing lots of stuff, almost like an old-school arcade game. XD
